摘　　要：采用电镀技术在建筑用Al-Cu-Mg硬铝合金型材上制备了Ni涂层和Ni/GO涂层,对比分析了基材和涂层的显微形貌、硬度、耐蚀性能和耐磨性能。结果表明,铝合金表面涂层中未见气孔或者裂纹等缺陷,整体较为致密,Ni涂层的C和O原子质量分数和原子分数都远小于Ni/GO涂层;表面镀Ni涂层和Ni/GO涂层都有助于提升表面硬度,Ni/GO涂层的硬度约为基材硬度的1.43倍;极化曲线和电化学阻抗谱测试结果表明,Ni涂层和Ni/GO涂层的耐蚀性能都优于基材,且Ni/GO涂层的耐蚀性最好;不同载荷作用下,Ni涂层和Ni/GO涂层的耐磨性能都优于基材,且Ni/GO涂层的耐磨性能最好。Ni coating and Ni/GO coating were prepared on Al-Cu-Mg duralumin alloy for building by electroplating technology,the micro-structure,hardness,corrosion resistance and wear resistance of the substrate and coating were compared and analyzed.The results showed that there were no defects such as pores or cracks in the surface coating of aluminum alloy,the whole coating was relatively compact,and the C and O atomic mass fraction and atomic percentage of Ni coating were far less than those of Ni/GO coating.The surface hardness of Ni coating and Ni/GO coating were helpful to improve the surface hardness,and the hardness of Ni/GO coating was about 1.43 times of that of base material.The polarization curve and electrochemical impedance spectrum test results showed that the hardness of Ni coating was about 1.43 times of that of base material.The corrosion resistance of Ni coating and Ni/GO coating was better than that of substrate,and the corrosion resistance of Ni/GO coating was the best,under different loads,the wear resistance of Ni coating and Ni/GO coating was better than that of substrate,and the wear resistance of Ni/GO coating was the best.
